Yahoo is the only thing green in a sea of red after beating earnings expectations yesterday, and option trading is strong at midday.
YHOO is up 5.6 percent to $16.65, its best level since the 52-week highs of exactly a year ago. Shares were down near 52-week lows at the start of September, falling to $14.60.
More than 173,000 options have traded so far today, already quadruple its full-day average of 43,000 in the last month. Calls outpace puts with volume of 103,000 contracts, but not by much.
